There is a phrase or saying that refers to humans accepting
technology. It contains a relation to the age at which the technology
is invented. Can you find it?

Before thirty, we accept it. After thirty, we dismiss it.

Or something. I read this on slashdot or somewhere similar in the past
couple of months, and using both my Google desktop search and the web
search (site:slashdot.org, 30, thirty, before, after, invented), I
find nothing. Please help me with web search expertise!

Thank you,

The one I found is by Douglas Adams, and it is this:

"...you would think we would learn the way these things work, which is this:

1. Everything that's already in the world when you're born is just normal
2. Anything that gets invented between then and before you turn thirty
is incredibly exciting and creative and with any luck you can make a
career out of it
3. Anything that gets invented after you're thirty is against the
natural order of things and the beginning of the end of civilisation
as we know it until it's been around for about ten years when it
gradually turns out to be alright really"

I found the quote here: http://www.cs.man.ac.uk/~hulld/quotes2004.htm.
The author of that site cites it as coming from an essay entitled "How
to Stop Worrying and Learn to Love the Internet" (by Douglas Adams),
which is here: http://www.douglasadams.com/dna/19990901-00-a.html.

Kudos. Can you post as an answer?
